Remark:1.Colling Condition: Chilled water in/out 12/7°C; Cooling water in/out 30/35°C;

2.Power supply: 3P-380V-50HZ;with voltage allowance ±10%,voltage dif between the phase lines±2%;

3.The data above is for R22, contact us if that for R134a,R407c and other refrigerant need;

4.There may be Changes for improvement without notice, confirm always before your order.

Water Cooled Chiller Introduction:

Features of Water Cooled Chiller:

1.30 sizes available ranging from 100kW to 1600kW cooling capacity;

2.Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.

3.Semi- hermetic screw compress or for all models. Each compressor is equipped with a crankcase heater and a thermal overload cut-out, the screw compress or is also complete with a built-in electronic protection with temperature sensor located directly in the motor win ding and on discharge line.

4.The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.

5.Shell and tube dry expansion type condense r, factory insulated with flexible close cell material.

6.The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display.

7.LCD display, touch screen control panel as standard.

8.Automatic operation dramatically reducing maintenance cost thanks t o reliable microprocessor system.

9.For the u nits with semi- hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions.

System Control of Water Cooled Chiller

1.Imaged system operation chart, showing the temperature of water in/out, the energy level of compressor run, on/off button, run time, alarm etc. And the remote turn on/off function is available. PC remote control is optional.

2.Notice for maintenance is indicated according to the accumulated run time of the compressor.It is convenience to maintenance.

3.The control system will automatically balance the run time for each compressor for mult-compressor unit.

Safety Protections of Water Cooled Chiller

1.Discharge check value:it prevents the discharged gas from going back after the compressor stops.

2.Phase lack protection:It protects the compressor for over high voltage, voltage dificiency, and phase lack.

3.Direction protection:It protects the compressor from damage resulted from Counter direction run.

4.Oil heater: It heats the oil before the unit start, keep the good lubrication for the unit before it runs.

5.Overheat protection inside the motor of the compressor: It protects the compressor from burning down for too high coil temperature for overload, or abnormal run condition.

6.High&low pressure protection: It protects the compressor and system against extreme run condition and trouble.

7.Freezing protection: It protects the unit form too low temperature of the water out, freezing may occerat some place, resulting in freezing breaking of the evaporator.

8.Water flow protect: It protects the unit from run without water flow.

9.High temperature of chilled water protection: It works to protect the compressor in case that the load is too large,the temperature of chilled water is too high. It may result in compressor failure without this protect in the case.
